Hanabi catches a cold, but both Iori and Konomi have to go to school, so Sonoa is left to take care of Hanabi. But Sonoa has some quirks to her personality, and things don't quite turn out as expected when she tries to take care of Hanabi.
Jeez, I just don't know what

quand on est avec toi.
Accidenti, proprio non so che dire
quando sono con te.
Eu só não sei o que falar
quando estou com você.
